>>re DUI tests, why don't US cops use Breathaliser machines like sensible people do, not all this touch your nose whilsty standing on one leg, with your arms out, and your eyes closed.....
i can't even do it when i'm sober !!!

We were playing a drinking game with the tests. If you failed the sobriety test you drank more and tried again....

Like 'mop spins' (take a broom or mop, hold it vertical, by the end of the handle, looking up at the 'head' (so you are staring up into the air). Spin round and round, counting (ten is hard, though I have seen someone do 100) and always looking up. Throw the mop down and try to jump over it.) Hours of fun and minor injuries.

US cops do use breathalizers. The 'standing on one leg' is part of the second of three tests given to drivers believed to be under the influence of alcohol.

When a driver is stopped for a traffic violation and the officer makes initial contact with the driver, the first test occurs. Are the eyes glassy or red? Is there an odor of alcoholic beverage? Does the driver slur his/her speech or fumble when gathering license or registration? Are there open alcoholic beverage containers in the vehicle? No single indicator means the driver is drunk or has been drinking, but two or three means it is possible and perhaps further investigation is needed.

The second test is the field sobriety test. This test varies a bit in each jurisdiction across the country, but usually includes basic motor skills tests such as walking in a straight line or balancing on one leg.

If the driver fails most/all of the field sobriety tests, it is time for a breathalizer or blood test.
